What Can Be Done About Gender Diversity in Computing?: A Lot!

The 2015 Grace Hopper celebration of women in computing is expected to bring together more than 12,000 — mostly female — computer scientists! But this impressive number should not be taken to mean all is well on the gender-diversity front. Far from it!

Ban ‘Naked’ Braces!

One afternoon early in 1990, one of the 100 or so 4ESS switches that handled U.S. long-distance traffic at the time hit a glitch and executed some untested recovery code. In the process the switch dragged its neighboring switches down, and the process cascaded across the country.

Computing Numerically with Functions Instead of Numbers

We present the Chebfun system for numerical computation with functions, which is based on a key idea: an analogy of floating-point arithmetic for functions rather than numbers.
